Typical Basement Tanking Diagram

Basement Tanking Specification

1. Walls prepared by scabbling back to substrate, removing old paint and plaster. This created a good "key" surface.


3. "Barrier Mortar" was applied to the wall to floor joint to achieve a water tight seal.

4. Render coat applied. Mixed 4:1 sharp sand & cement incorporating 3:1 clean water & Kingfisher "K-X11". Important: Do not leave more than 48 hrs before proceeding step 5.

5. Kingfisher "Aquatech" basement tanking membrane applied, having allowed render to cure overnight. "Aquatech" was mixed with 5:1 water and "K-X11" using a powered paddle. Two coats required.

6. Kingfisher "Dry wall" renovating plaster was applied to finish. Note: Only cement and lime based renovating plasters can be used onto the Basement Tanking system.
